SUNERGY is a pan-European R&I initiative working to enable a circular economy through the sustainable production of fossil-free fuels and commodity chemicals from renewable energy (sunlight, wind) and abundant molecules (CO2, water, nitrogen). The approach is based on scientific breakthroughs tightly coupled to scale-up by increasing the technological readiness of renewable conversion technologies for the large-scale sustainable manufacturing of hydrogen, synthetic hydrocarbons, and ammonia. It builds on an open community of currently 300+ supporters from industry, academia and society, across sectors, and geographical areas.

SUNERGY has been supported in its activities by the Horizon Europe SUNER-C Coordination and Support Action (CSA, Grant Agreement N°101058481, June 2022 à May 2025), covering both fuels produced via indirect processes (e-fuels, thermochemical processes) and direct solar fuels (direct conversion of solar energy to chemical energy, i.e., artificial photosynthesis). A new CSA project, SUN2X-SET, is expected to begin its activities in May 2026 for a duration of two years. This project will focus more on Direct Solar Fuels with the main objective of continuing the activities under the umbrella of the Strategic Energy Technology Plan (SET Plan). 

The contribution will introduce the SUNERGY initiative, the main achievements of the SUNER-C project and the SUN2X-SET project taking into account the current context and policies on hydrogen, CCU and sustainable fuels and chemicals.
